HWPOISON: Add a madvise() injector for soft page offlining
Process based injection is much easier to handle for test programs, who can first bring a page into a specific state and then test. So add a new MADV_SOFT_OFFLINE to soft offline a page, similar to the existing hard offline injector. Signed-off-by: Andi Kleen <ak@linux.intel.com>
